Msd Ignition 85551 Distributor

This is our most popular performance distributor! The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances. For high RPM stability, a 0.500 Inch steel shaft is supported by a sealed ball bearing and a long sintered bushing. This shaft also receives a QPQ coating for friction reduction and resistance to corrosion. A precision machined reluctor is attached to the shaft which triggers the magnetic pickup mounted in the housing. This high output magnetic pickup is the most accurate way to trigger your ignition. Plus, with no moving parts to wear or adjust, the pick up is maintenance free! Just above the pick up is MSD’s adjustable mechanical advance assembly. Different springs and stop bushings are supplied so you can tune an advance curve to match your application.
